@yanglichuan Where did you call TedPermission?

[zenkhas]

Having same problem. This is where I'm calling it:

@Override public void setUserVisibleHint(boolean isVisibleToUser) { super.setUserVisibleHint(isVisibleToUser);

    if (isVisibleToUser) {

        new TedPermission(getActivity())
                .setPermissionListener(permissionlistener)
                .setDeniedMessage("If you reject permission, you can not use this service\n\nPlease turn on permissions at [Setting] > [Permission]")
                .setPermissions(Manifest.permission.READ_CONTACTS, Manifest.permission.READ_CALL_LOG, Manifest.permission.READ_SMS)
                .check();
    }
}

same problem here called from fragment onCreate new TedPermission(getActivity()) .setPermissionListener(permissionListener) .setDeniedMessage(getString(R.string.fragment_move_gps_denied_error_message)) .setPermissions(Manifest.permission.ACCESS_COARSE_LOCATION, Manifest.permission.ACCESS_FINE_LOCATION) .check();

same issue.

[ParkSangGwon]

@yanglichuan @zenkhas @Bkrickl @hjbaek Can you upload your project file?(by zip file) I had test but I can not find error. If you upload error sample project, I will find and fix it

[serendipper16]

저도 비슷한 경우인 것 같은데 NPE가 발생해서 코멘트 남깁니다.

발생상황: fragment의 엑션바 menu아이템 클릭시 TedPermission 호출 후 권한승인되면 엑티비티 실행하는 로직에서 발생. 디버그 모드일때는 정상작동하나 릴리즈 모드로 실행시 발생

실행코드

@Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case R.id.action_map: / 권한체크 / new TedPermission(getContext()) .setPermissionListener(new PermissionListener() { @Override public void onPermissionGranted() { startActivity(new Intent(getContext(), MapActivity.class)); }

                        @Override
                        public void onPermissionDenied(ArrayList<String> deniedPermissions) {

                        }
                    })
                    .setDeniedMessage("권한이 승인되지 않아  서비스를 실행할 수 없습니다.\n권한설정은 [설정] > [권한]에서 변경하실 수 있습니다.")
                    .setGotoSettingButtonText("설정")
                    .setPermissions(Manifest.permission.ACCESS_FINE_LOCATION)
                    .check();
            break;
    }

    return super.onOptionsItemSelected(item);
}

@serendipper16 getContext()가 아닌 getActivity() 나 Activity이름.this로 context를 지정해도 같은오류가 발생하시나요?

[serendipper16]

좀전에 다시 테스트 해봤는데 getActivity()를 해도 여전히 죽으며 fragment에서 호출중인데 MainActivity.this는 어떻게 호출해야 하는지 모르겠습니다. getContext()로 작업시 debug에서는 문제가 없었으나 빌드 후 release로 배포시에 죽는 현상을 발견하였습니다.

@serendipper16 혹시 Proguard를 사용중이신가요?

[serendipper16]

아 네 release모드에 proguard 설정이 되어있었어서 발생했던 것 같아요.

[ParkSangGwon]

@serendipper16 Readme의 proguard 설정을 보시고 그대로 적용해보시면 otto관련 이슈는 없을것 같습니다.
